Cloudflare launches Kitesurf, a browser built for AI agents

Cloudflare has introduced Kitesurf, a new cloud-hosted web browser specifically designed for AI agents, rather than as a consumer alternative to Chrome. Kitesurf integrates a modular rendering engine from Blitz, Firefox’s CSS parser Stylo, and Boa JS, a Rust ECMAScript engine, with all other components running within Cloudflare Workers. Despite being new, Kitesurf already passes over 215,000 web platform tests and continues to improve weekly.
